Time (us) to draw a 200x200 src onto an image.RGBA dst with the Over
operator. Each case was measured three separate times, and the sorted
times are reported.

Fill case (where src is an image.ColorImage):
Before:
7438, 7511, 7526
After:
3073, 3087, 3102

Copy case (where src is an image.RGBA):
Before:
9506, 9510, 9563
After:
5262, 5300, 5344

Specifically:
- Simplified definition of comparison compatibility and folded into
  section on comparison operators since it's only used there.

This is a small language change/cleanup. As a consequence:
- An interface value may now be compared against a non-interface value.
- Channels with opposite directions cannot be compared directly anymore
  (per discussion with rsc).

    charclass to avoid unnecessarily iterating over ranges.
    Also, use the fact that IntVector is an []int to avoid method calls.
    On my machine, this brings us from ~27500 ns/op to ~17500 ns/op in the benchmark I've added (it is also faster in the case where a range check
    doesn't help, added a benchmark for this too.)

    I'd also like to propose that "[]", and "[^]" be disallowed. They aren't useful as far as I can tell, they aren't widely supported, and they make reasoning about character classes a bit more complicated.

On error, ReadSlice is defined to return the available data
and advance past that data, but it was not behaving that
way for err == ErrBufferFull, making it harder for callers to
handle well.

	(compiler bug stops complex from being renamable,
	so it can't be tested but the code is there)
- %q %x for strings

  as a unix signal with name SIGQUEUE. Now it is ignored.

Also, move Do() to vector.go, so that Do() for IntVector and StringVector
is autogenerated.

The only files edited are Makefile, defs.go, and vector.go. The rest are
autogenerated with "make generate".
